| 13:12 | xobs | On a Hummingboard, should the root controller show up even without a PCIe card inserted? |
| 13:14 | xobs | On this board, running "lspci -v" shows nothing, and "dmesg" shows "probe of 1ffc000.pcie failed with error -22". This is on 3.14.60-fslc-imx6-sr, on a fresh install. Though it looks like a dist-upgrade installs a new kernel, so I'll give that a shot first. |
| 13:26 | jnettlet | xobs, nope it shuts itself off to save power |
| 13:26 | xobs | jnettlet, anyway to disable that, and have it stay on? I'd like "rescan" to work. |
| 13:27 | jnettlet | xobs, should be trivial to patch into it, but the interface doesn't support hotplugging |
| 13:27 | jnettlet | I have tried and the SOC resets |
| 13:29 | xobs | Oh? I wonder why it's different from Novena. I know in the past, I have a SATA card here that only comes up on Novena if you continuously rescan while shorting out Rx+ and Rx-. Eventually it enumerates. |
| 13:37 | jnettlet | xobs, the behaviour is caused by a patch introduced by NXP. This has been done more sane in the mainline driver. It is an easy fix |
| 13:38 | jnettlet | it is in drivers/pci/host/pci-imx6.c in imx6_pcie_host_init() |
| 13:38 | jnettlet | just don't return the ret value |
| 13:52 | xobs | Thanks. I'll rebuild and give it a shot. |
